Patent DE-4006599-A1 (DE)
Inventor: TANI NOBUHIRO
IPC: H01L27/14
Filed: 1990-03-02
Abstract: In an interline CCD imaging device suitable for use in a still camera, the vertical transfer portions 14, which serve to take accumulated electrical charges corresponding to the quantity of light received photosensors 12 and transfer them to an output horizontal transfer region 16 one line at a time, are provided with transparent electrodes and are themselves photosensitive. Either the photosensors or the transfer portions are provided with sets of three colour filters, whereby luminance and colour signals can be obtained sequentially once the camera shutter has closed, the first obtained signal being stored for combination with the second signal. The arrangement provides increased horizontal resolution and an efficient use of incident light. <IMAGE>

Title: Dust removal filter for hot gas - composed of metallic or ceramic elements assembled in a honeycomb body in a filer housing
Inventor: GIESE MANFRED
IPC: B01D46/24
Filed: 1990-03-19
Abstract: Metallic or ceramic dust filters used to clean gas at high temps. cannot be cleaned as easily as cloth filters used at lower temps. The novelty is that metallic or ceramic filter elements are located within open hexagonal tubes which are assembled into a honeycomb body welded together at the upper end and located within a filter housing. In one embodiment, the filter elements are located within hexagonal tubes. Raw gas-laden dust enters via the inlet and leaves after cleaning through the egress above the honeycomb assembly. The spaces remaining between the ends of the hexagonal tubes and the filter case are sealed by sheet metal. USE/ADVANTAGE - Dust once removed can drop away for collection to prevent recirculation of dust and reduce  the incidence of filter blockage during the continued filtration process. This reduces the frequency with which the filter must be cleaned.

Title: Automated prodn. of boards from wooden blocks of glued strips - by forming sheets from blocks, inserting glued core layer on one block sheet, placing second block sheet on top, and pressing
Inventor: RITTERHOFF HEINRICH
IPC: B32B21/04
Filed: 1990-03-30
Abstract: Process for producing boards from layers of wooden blocks as follows. The lower cover layer is placed on a conveyor sheet, a ready-glued-up core layer is placed on top, and the top cover layer plus the top caul are placed in position by means of a vacuum conveyor carriage, the cover layers having been placed together in readiness beforehand. At the start, the one cover layer is laid up from its strips into a block, with the visible faces stacked together; this block is passed through a glue spreader which applies the glue to the edges of the strips; the strips are next assembled together into the cover layers whilst, in parallel operation, the core layer is glued on top and bottom faces in a separate prodn. line. For the prodn. of furniture panels a number of strips are taken from a magazine (25) and stacked on a table (17) before being passed through the glue spreader (18) as one block. The strips are next joined with one cover layer (at 19). The same procedure applies to both top and bottom cover. At the same time a vacuum conveyor (16) brings a caul, lays it on the stack (6) and justifies the parts. ADVANTAGE - In the process the strips used are all processed automatically and in one operation. They are efficiently treated and can be pressed together to produce furniture panels or formwork boards.

Title: Pressure modulator for hydraulically operated vehicle brake systems - includes at least one relieving piston respectively working with shaft and electromagnetically controlled friction coupling
Inventor: BUECHS HUBERT DR
IPC: B60T8/42
Filed: 1990-08-14
Abstract: The relieving piston (3) reacts on two pressure chambers (1, 7) so that with the piston movement, one pressure chamber experiences a vol. increase and the other pressure chamber a redn. in vol. The relieving piston is held in its original position by a spring in the pressure chamber. If the electronic circuit identifies a risk of brake locking, the friction coupling (10) is electromagnetically excited, to produce a downward movement of the relieving piston, to increase the vol. in the pressure chamber (1). The pressure chamber (1) is used for ABS regulation and the other chamber (7) for ASR regulation. A changeover valve (4) is arranged between the pressure modulator and the wheel cylinder on one side and between the pressure modulator and the main cylinder (HZ) on the other side. The changeover valve is an electrically controlled 4/2 way valve. USE/ADVANTAGE - With simple and compact construction, can be used also for ASR as well as ABS systems or combination of both systems.

IPC: C07F7/22
Filed: 1991-01-22
Abstract: The invention concerns a method of synthesizing directly organo-tin chlorides of the formula RnSnCl4-n, in which n = 1 or 2 and R is a straight-chain, branched-chain or cycloaliphatic alkyl rest with 4 to 18 C-atoms, by reacting tin(II)-chloride with alkyl chlorides. The method is characterized in that the reaction is carried out in the presence of amines of the general formula A: R<1>aN[(CH2CH2O)m CH2CH2OR<2>]3-a and/or substituted ammonium chlorides of the formula B: R<1>bN[(CH2CH2O)mCH2CH2OR<2>]4-b Cl in which a = 0, 1 or 2; b= 0, 1, 2 or 3; R<1> is a straight-chain, branched-chain or cycloaliphatic alkyl group with 2 to 24 C-atoms, or an aryl, alkylaryl or substituted-aryl group, and if a = 2 or b = 2 or 3, the R<1> groups may be the same or different; R<2>=H is a straight-chain or branched-chain alkyl group with 1 to 20 C-atoms, or an aryl, substituted-aryl or alkylaryl group; and m = 1 to 20. Organo-tin chlorides produced in this way are particularly suitable for use as intermediates in the preparation of thermostabilizers for PVC resins.

Title: Cooled plunger piston for IC engine - has sepd. piston upper part and shaft and oil ring limiter
Inventor: KEMNITZ PETER
IPC: F02F3/22
Filed: 1991-03-16
Abstract: The piston upper part (1) and the piston shaft (2) are articulatedly connected to each other, the upper part being of steel or iron. From the piston base extends a ring strip accommodating the ring grooves in the direction of the piston bolt, above which it ends. The ring strip limits a cooling oil space which is open towards the piston shaft, but which is coverable. The radial inner limit of the cooling oil space forms a ring rib which evolves into two naves opposite to the piston bolt. In the piston base, a combustion chamber hollow is formed which is partly limited by the ring rib. The piston upper part is guided exclusively in the area of the first ring step (4) in the engine cylinder bore, and the height of this step is between 3 and 7% of the dia. of the piston. USE/ADVANTAGE - For internal combustion engines, to improve the guiding of a plunger piston with consequent redn. in oil consumption.

IPC: B23D49/16
Filed: 1991-03-19
Abstract: A reciprocating saw is provided with a counterbalanced reciprocating drive having a jackshaft (24) on which primary and secondary wobble plates (30) are mounted. The wobble plates (30) drive a reciprocating saw spindle (40) and a concentric counterweight (46) in opposite directions to cancel out the induced vibrations. The spindle (40) reciprocates in a bearing sleeve (50) having a slot (52) through which the primary wobble plate arm (34) projects through a longitudinal slot (54) in the spindle (40) and engages the opposite side (38) of the spindle so the spindle cannot rotate as it reciprocates. The counterweight (46) slides on the outside of the sleeve (50) and has a slot (58) which slides over the primary arm (34). The secondary wobble plate arm (35) drives the counterweight (36). The arms (34 and 35) are out of alignment to permit their strokes to overlap without collision. The wobble plates (30) are angled out of 180 DEG C so the spindle (40) and counterweight (46) reverse at the same time. The cutting stroke and speed of the saw are increased and vibration is insignificant. The spindle drive has utility apart from the counterbalanced drive. <IMAGE>
